"Kocham mojego chłopaka."

Translation: I love my boyfriend.

[immerweiter]

i think it is genitive, there are verbs that require the genitive

[conor.raff]

No this verb is transitive, which means the object "boyfriend" is in the accusative.

but because its an masc. singular animate noun,. it takes the same declension as genitive

m. sg. gen. an. = "-a"
